when my fuze is switched off and i connect it to pc to transfer tunes, its in stock player usb connected mode, not rb. Therefore it takes ages to do its refresh database thing and then i have to initialize the media library in rb also aftwerwards Zzzzz...

With clip zip i cant recall it doing this, it went into rb usb connected mode and therefore i only had to do the initialise database thing after.

You can just skip the refresh database thing in the stock firmware by holding the power switch till it turns off,then turn it on again and boot up into Rockbox. When I had mine,I always searched stuff by files so database refresh was always never needed. But the USB thing never worked well with the Fuze+Rockbox,so it isn't included.As for the Clip+,it has more success with RB USB connection than the Fuze.

When you say 'current bootloader' what do you mean exactly? I mean i have the latest rb for fuze installed (just did it like a month ago), is the bootloader a single specific file or summin available from the rb website?

Run the automated installer again. Under the Installation tab pick Install the bootloader. You usually only need to do that once but the bootloader was updated to boot to Rockbox instead of the OF after USB support was enabled.
